Maintenance
Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in
the canister are drawn into the surge
tank through the purge control sole-
noid valve.
Purge Control Solenoid Valve(PCSV)
The purge control solenoid valve is
controlled by the Engine Control
Module (ECM); when the engine
coolant temperature is low during
idling, the PCSV closes so that evap-
orated fuel is not taken into the
engine. After the engine warms up
during ordinary driving, the PCSV
opens to introduce evaporated fuel to
the engine.
3. Exhaust emission control system
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
while maintaining good vehicle per-
formance.
Vehicle modifications
This vehicle should not be modified.
Modification of your vehicle could
affect its performance, safety or
durability and may even violate gov-
ernmental safety and emissions reg-
ulations.
In addition, damage or performance
problems resulting from any modifi-
cation may not be covered under
warranty.
If you use unauthorized electronic
devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic devices.
Engine exhaust gas precautions
(carbon monoxide)
Carbon monoxide can be present with other exhaust fumes.
Therefore, if you smell exhaust
fumes of any kind inside your vehi-
cle, have it inspected and repaired
immediately. If you ever suspect
exhaust fumes are coming into
your vehicle, drive it only with all
the windows fully open. Have your
vehicle checked and repaired
immediately.
WARNING - Exhaust
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
on this page to avoid CO poi-
soning.

Do not operate the engine in con-
fined or closed areas (such as
garages) any more than what is
necessary to move the vehicle in or
out of the area.
When the vehicle is stopped in an open area for more than a short
time with the engine running,
adjust the ventilation system (as
needed) to draw outside air into the
vehicle.
Never sit in a parked or stopped vehicle for any extended time with
the engine running.
When the engine stalls or fails to start, excessive attempts to restart
the engine may cause damage to
the emission control system.Operating precautions for catalyt-
ic converters (if equipped)
Your vehicle is equipped with a cat-
alytic converter emission control
device.
Therefore, the following precautions
must be observed: Use only UNLEADED FUEL for
gasoline engines.
Do not operate the vehicle when there are signs of engine malfunc-
tion, such as misfire or a noticeable
loss of performance.
Do not misuse or abuse the engine. Examples of misuse are
coasting with the ignition off and
descending steep grades in gear
with the ignition off.
Do not operate the engine at high idle speed for extended periods (5
minutes or more).
Do not modify or tamper with any part of the engine or emission con-
trol system. All inspections and
adjustments must be made by an
authorized Kia dealer.
Avoid driving with a extremely low fuel level. Running out of fuel could
cause the engine to misfire, dam-
aging the catalytic converter.
Failure to observe these precautions
could result in damage to the catalyt-
ic converter and to your vehicle.
Additionally, such actions could void
your warranties.
WARNING- Fire
Do not park, idle or drive the vehicle over or near flamma-
ble objects, such as grass,
vegetation, paper, leaves, etc.
A hot exhaust system can
ignite flammable items under
your vehicle.
Also, do not remove the heat sink around the exhaust sys-
tem, do not seal the bottom of
the vehicle or do not coat the
vehicle for corrosion control.
It may present a fire risk under
certain conditions.
WARNING- Catalytic
converter
Keep away from the catalytic
converter and exhaust system
while the vehicle is running or
immediately thereafter. The
exhaust and catalytic systems
are very hot and may burn you.

RECOMMENDED LUBRICANTS AND CAPACITIES
To help achieve proper engine and powertrain performance and durability, use only lubricants of the proper quality.
The correct lubricants also help promote engine efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.
*1Refer to the recommended SAE viscosity numbers on the next page.
*2Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute
to fuel economy by reducing the amount of fuel necessary to overcome engine friction. Often, these improvements
are difficult to measure in everyday driving, but in a year’s time, they can offer significant cost and energy savings.

Recommended SAE viscosity
numberEngine oil viscosity (thickness) has
an effect on fuel economy and cold
weather operating (engine start and
engine oil flowability). Lower viscosi-
ty engine oils can provide better fuel
economy and cold weather perform-
ance, however, higher viscosity
engine oils are required for satisfac-
tory lubrication in hot weather.Using oils of any viscosity other than
those recommended could result in
engine damage.
When choosing an oil, consider the
range of temperature your vehicle
will be operated in before the next oil
change. Proceed to select the rec-
ommended oil viscosity from the
chart.
CAUTION
Always be sure to clean the area
around any filler plug, drainplug, or dipstick before check-ing or draining any lubricant.This is especially important industy or sandy areas and whenthe vehicle is used on unpavedroads. Cleaning the plug anddipstick areas will prevent dirtand grit from entering theengine and other mechanismsthat could be damaged.

*1. For better fuel economy, it is recommended to use the engine oil of
a viscosity grade SAE 5W-20 (API SM / ILSAC GF-4). However, if
the engine oil is not available in your country, select the proper
engine oil using the engine oil viscosity chart.

Trip interruption
Trip interruption expense benefits are provided in the
event that a warranty-related disablement occurs more
than 150 miles from your home, and the repairs require
more than 24 hours to complete. Reasonable reimburse-
ment is included for meals, lodging, or rental car expens-
es. Trip interruption coverage is limited to $100 per day
subject to a three day maximum limit per incident. You
must contact the Kia Roadside Assistance Center to
obtain pre-authorization of expenses. Once the Kia
Roadside Assistance Center gives authorization for trip
interruption benefits, they will assist you in making the

Registering your vehicle in a foreign country
If you plan to register your vehicle in a foreign country,
you should confirm that it conforms to the regulations in
that country. Even if you successfully register the vehicle
in a foreign country, you may experience the following
problems and should therefore consider the possibility of
having to deal with them:1. The fuel specified for your vehicle may be unavailable.
If other than the specified fuel is used, it could cause
damage to the engine, the fuel injection system, and
other fuel-related parts which may not be covered
under your New Vehicle Emissions Limited Warranty.
2. We must, therefore, clearly state that when you leave the country in which you purchased your Kia new and
register it in another country, problems arising from the
use of fuel other than the specified fuel are not subject
to manufacturer’s warranty. Because vehicles like
yours may not be marketed in the new country of reg-
istration, parts, servicing techniques and tools neces-
sary to maintain and repair your vehicle may be
unavailable.
Even if vehicles like yours are sold there, mechanical
specifications required by the government may vary
enough from the country of purchase to cause addi-
tional problems.
3. There may not be an Authorized Kia Dealer in the area in which you plan to register your vehicle. You may
additionally experience difficulty in obtaining services
in a foreign country for any number of reasons.
Further, we cannot assume any responsibility for prob-
lems that result from unsatisfactory service or lack of
service outside of the United States.
